WINRES-20B BLUE is designed using advanced engineering technology to measure the winding resistance of transformers. WINRES-20B BLUE can measure current, voltage, power transformer windings and shunt resistors. Applying up to 20A Direct Current allows WINRES-20 BLUE to measure the resistance of the transformers fast and accurate.
The smart design of the WINRES-20B BLUE makes easier to determine the end of measurement automatically according to users’ decision. WINRES-20B BLUE can measure two resistance values simultaneously with its two voltage measurement channels. Users can prefer to test two primary or two secondary or one primary and one secondary winding according to the configuration of transformers.
Beginning from 0.1 μΩ resistances, WINRES-20B BLUE can measure up to 100,000 Ω resistances. WINRES-20 BLUE discharges the measured circuit after each test. For inductive load, WINRES-20B BLUE can demagnetise the load. The temperature measurement input enables one to connect an optional sensor to WINRES-20B BLUE and perform temperature correction automatically. WINRES-20B BLUE’s intelligent software allows controlling the current flow if there is a failure in the current circuit. With this feature, WINRES-20B BLUE procures added safety to users.
A 7-inch TFT touch display allows WINRES-20B BLUE to show all measurement results on a single screen. WINRES-20B BLUE can be controlled by USB and built-in Bluetooth interface and users can record/store measurement results. In case setting up Laptop or PC for the field test is difficult; users can record data to the device’s internal memory (up to 100 Test Records) or to an external USB flash memory.
With the HighTest Data Management Platform (DMP Software), users can control WINRES-20B BLUE, analyse and manage measurement results using a PC. Operators can easily print the measurement results with the 2.28-inch built-in Printer of WINRES-20B. WINRES-20B BLUE has a built-in battery power feature which allows users to make tests even when there is no electricity. Multi-language capability and user-friendly operation menu make it easy to control WINRES-20B BLUE, even by less trained staffs.
Three-Phase Adaptor TPA-03 (optional accessory) allows connecting all primary and secondary sides concurrently, whereby users can select either to test the resistance of all phases or selective phases. With the TPA-03 option, WINRES-20B BLUE can control tap changer (raise and lower) with its tap changer outputs.
WINRES-20B BLUE is a light, compact and rugged device with the protection class IP67 (case closed).
